lib/backup/azremote: follow-up for 5fd3aef549
- Mention that credentials can be configured via env variables at both vmbackup and vmrestore docs.

- Make clear that the AZURE_STORAGE_DOMAIN env var is optional at https://docs.victoriametrics.com/vmbackup/#providing-credentials-via-env-variables

- Use string literals as is for env variable names instead of indirecting them via string constants.
  This makes easier to read and understand the code. These environment variable names aren't going to change
  in the future, so there is no sense in hiding them under string constants with some other names.

- Refer to https://docs.victoriametrics.com/vmbackup/#providing-credentials-via-env-variables in error messages
  when auth creds are improperly configured. This should simplify figuring out how to fix the error.

- Simplify the code a bit at FS.newClient(), so it is easier to follow it now.
  While at it, remove the check when superflouos environment variables are set, since it is too fragile
  and it looks like it doesn't help properly configuring vmbackup / vmrestore.

- Remove envLookuper indirection - just use 'func(name string) (string, bool)' type inline.
  This simplifies code reading and understanding.

- Split TestFSInit() into TestFSInit_Failure() and TestFSInit_Success(). This simplifies the test code,
  so it should be easier to maintain in the future.

lib/protoparser/graphite: follow-up for 476faf5578
- Clarify the description of -graphite.sanitizeMetricName command-line flag at README.md
- Do not sanitize tag values - only metric names and tag names must be sanitized,
  since they are treated specially by Grafana. Grafana doesn't apply any restrictions on tag values.
- Properly replace more than two consecutive dots with a single dot.
- Disallow unicode letters in metric names and tag names, since neither Prometheus nor Grafana
  do not support them.

Fix inconsistent error handling in Storage.AddRows() (#6583)
`Storage.AddRows()` returns an error only in one case: when
`Storage.updatePerDateData()` fails to unmarshal a `metricNameRaw`. But
the same error is treated as a warning when it happens inside
`Storage.add()` or returned by `Storage.prefillNextIndexDB()`.

This commit fixes this inconsistency by treating the error returned by
`Storage.updatePerDateData()` as a warning as well. As a result
`Storage.add()` does not need a return value anymore and so doesn't
`Storage.AddRows()`.

Additionally, this commit adds a unit test that checks all cases that
result in a row not being added to the storage.

docs/CONTRIBUTING.md: mention that docs/CHANGELOG.md shouldn't contain technical details for the changes
The purpose of docs/CHANGELOG.md is to provide VictoriaMetrics users clear and concise information
on what's changed at VictoriaMetrics components. Technical details of the change are unclear
to most of VictoriaMetrics users, who are not familiar with VictoriaMetrics source code.
These details complicate reading the docs/CHANGELOG.md by ordinary users, so do not clutter
the changelog with technical details. If the user wants technical details, he can click
the link to the related GitHub issue and/or pull request and dive into all the details he wants.

Revert "app/vmauth: reader pool to reduce gc & mem alloc (#6533)"
This reverts commit 4d66e042e3.

Reasons for revert:

- The commit makes unrelated invalid changes to docs/CHANGELOG.md
- The changes at app/vmauth/main.go are too complex. It is better splitting them into two parts:
  - pooling readTrackingBody struct for reducing pressure on GC
  - avoiding to use readTrackingBody when -maxRequestBodySizeToRetry command-line flag is set to 0

Let's make this in the follow-up commits!

lib/promscrape/discovery/yandexcloud: follow-up for 070abe5c71
- Obtain IAM token via GCE-like API instead of Amazon EC2 IMDSv2 API,
  since it looks like IMDBSv2 API isn't supported by Yandex Cloud
  according to https://yandex.cloud/en/docs/security/standard/authentication#aws-token :

  > So far, Yandex Cloud does not support version 2, so it is strongly recommended
  > to technically disable getting a service account token via the Amazon EC2 metadata service.

- Try obtaining IAM token via GCE-like API at first and then fall back to the deprecated Amazon EC2 IMDBSv1.
  This should prevent from auth errors for instances with disabled GCE-like auth API.
  This addresses @ITD27M01 concern at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5513#issuecomment-1867794884

- Make more clear the description of the change at docs/CHANGELOG.md , add reference to the related issue.

P.S. This change wasn't tested in prod because I have no access to Yandex Cloud.
It is recommended to test this change by @ITD27M01 and @vmazgo , who filed
the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5513

Revert "deployment: build image for vmagent streamaggr benchmark (#6515)"
This reverts commit 6b128da811.

Reason for revert: this complicates and slows down CI/CD without giving significant benefits in return.

The idea of automatic building, publishing and deploying Docker images to our playground on every pull request
and commit isn't very bright because of the following reasons:

- It slows down CI/CD pipeline
- It increases costs on CPU time spent at CI/CD pipeline
- It contradicts goal #7 at https://docs.victoriametrics.com/goals/#goals and non-goal #8 at https://docs.victoriametrics.com/goals/#non-goals

The previous workflow was much better - if we need to deploy some new Docker image at playground or staging environment,
then just __manually__ build and deploy the needed Docker image there. If the manual process requires making too many
steps, then think on how to automate these steps into a single Makefile command.

app/vmauth: follow-up for 3a45bbb4e0
- Move the test for SRV discovery into a separate function. This allows verifying round-robin discovery across SRV records.
- Restore the original netutil.Resolver after the test finishes, so it doesn't interfere with other tests.
- Move the description of the bugfix into the correct place at docs/CHANGELOG.md - it should be placed under v1.102.0-rc2
  instead of v1.102.0-rc1.
- Remove unneeded code in URLPrefix.sanitizeAndInitialize(), since it is expected this function is called only once
  for finishing URLPrefix initializiation. In this case URLPrefix.nextDiscoveryDeadline and URLPrefix.n are equal to 0
  according to https://pkg.go.dev/sync/atomic#Uint64
- Properly fix the bug at URLPrefix.discoverBackendAddrsIfNeeded() - it is expected that hostToAddrs map uses
  the original hostname keys, including 'srv+' prefix, so it shouldn't be removed when looping over up.busOriginal.
  Instead, the 'srv+' prefix must be removed from the hostname only locally before passing the hostname to netutil.Resolver.LookupSRV.

Revert "lib/protoparser/opentelemetry/firehose: escape requestID before returning it to user (#6451)"
This reverts commit cd1aca217c.

Reason for revert: this commit has no sense, since the firehose response has application/json content-type,
so it must contain JSON-encoded timestamp and requestId fields according to https://docs.aws.amazon.com/firehose/latest/dev/httpdeliveryrequestresponse.html#responseformat .
HTML-escaping the requestId field may break the response, so the client couldn't correctly recognize the html-escaped requestId.

app/vmagent/remotewrite: follow-up for f153f54d11
- Move the remaining code responsible for stream aggregation initialization from remotewrite.go to streamaggr.go .
  This improves code maintainability a bit.

- Properly shut down streamaggr.Aggregators initialized inside remotewrite.CheckStreamAggrConfigs().
  This prevents from potential resource leaks.

- Use separate functions for initializing and reloading of global stream aggregation and per-remoteWrite.url stream aggregation.
  This makes the code easier to read and maintain. This also fixes INFO and ERROR logs emitted by these functions.

- Add an ability to specify `name` option in every stream aggregation config. This option is used as `name` label
  in metrics exposed by stream aggregation at /metrics page. This simplifies investigation of the exposed metrics.

- Add `path` label additionally to `name`, `url` and `position` labels at metrics exposed by streaming aggregation.
  This label should simplify investigation of the exposed metrics.

- Remove `match` and `group` labels from metrics exposed by streaming aggregation, since they have little practical applicability:
  it is hard to use these labels in query filters and aggregation functions.

- Rename the metric `vm_streamaggr_flushed_samples_total` to less misleading `vm_streamaggr_output_samples_total` .
  This metric shows the number of samples generated by the corresponding streaming aggregation rule.
  This metric has been added in the commit 861852f262 .
  See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6462

- Remove the metric `vm_streamaggr_stale_samples_total`, since it is unclear how it can be used in practice.
  This metric has been added in the commit 861852f262 .
  See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6462

- Remove Alias and aggrID fields from streamaggr.Options struct, since these fields aren't related to optional params,
  which could modify the behaviour of the constructed streaming aggregator.
  Convert the Alias field to regular argument passed to LoadFromFile() function, since this argument is mandatory.

- Pass Options arg to LoadFromFile() function by reference, since this structure is quite big.
  This also allows passing nil instead of Options when default options are enough.

- Add `name`, `path`, `url` and `position` labels to `vm_streamaggr_dedup_state_size_bytes` and `vm_streamaggr_dedup_state_items_count` metrics,
  so they have consistent set of labels comparing to the rest of streaming aggregation metrics.

- Convert aggregator.aggrStates field type from `map[string]aggrState` to `[]aggrOutput`, where `aggrOutput` contains the corresponding
  `aggrState` plus all the related metrics (currently only `vm_streamaggr_output_samples_total` metric is exposed with the corresponding
  `output` label per each configured output function). This simplifies and speeds up the code responsible for updating per-output
  metrics. This is a follow-up for the commit 2eb1bc4f81 .
  See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6604

- Added missing urls to docs ( https://docs.victoriametrics.com/stream-aggregation/ ) in error messages. These urls help users
  figuring out why VictoriaMetrics or vmagent generates the corresponding error messages. The urls were removed for unknown reason
  in the commit 2eb1bc4f81 .

- Fix incorrect update for `vm_streamaggr_output_samples_total` metric in flushCtx.appendSeriesWithExtraLabel() function.
  While at it, reduce memory usage by limiting the maximum number of samples per flush to 10K.

lib/{storage,mergeset}: do not allow setting dataFlushInterval to values smaller than pending{Items,Rows}FlushInterval
Pending rows and items unconditionally remain in memory for up to pending{Items,Rows}FlushInterval,
so there is no any sense in setting dataFlushInterval (the interval for guaranteed flush of in-memory data to disk)
to values smaller than pending{Items,Rows}FlushInterval, since this doesn't affect the interval
for flushing pending rows and items from memory to disk.

app/vmagent/remotewrite: do not spend CPU time on an attempt to send data to blocked queue if some queues are unblocked
Previously remotewrite.TryPush() was trying to send data to remote storages with blocked persistent queues,
if some persistent queues to other remote storage systems were unblocked. This resulted in excess CPU usage
on relabeling and stream aggregation for the remote storage with blocked queues.

The solution is to check whether some peristent storages have blocked queues and skip them before applying
per- -remoteWrite.url relabeling and streaming aggregation.

While at it, properly update per- -remoteWrite.url vmagent_remotewrite_samples_dropped_total and vmagent_remotewrite_push_failures_total
counters when global streaming aggregation cannot send data to remote storage systems because of blocked queues.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5467 and https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6268 .

lib/streamaggr: follow-up for 9c3d44c8c9
- Consistently enumerate stream aggregation outputs in alphabetical order across the source code and docs.
  This should simplify future maintenance of the corresponding code and docs.

- Fix the link to `rate_sum()` at `see also` section of `rate_avg()` docs.

- Make more clear the docs for `rate_sum()` and `rate_avg()` outputs.

- Encapsulate output metric suffix inside rateAggrState. This eliminates possible bugs related
  to incorrect suffix passing to newRateAggrState().

- Rename rateAggrState.total field to less misleading rateAggrState.increase name, since it calculates
  counter increase in the current aggregation window.

- Set rateLastValueState.prevTimestamp on the first sample in time series instead of the second sample.
  This makes more clear the code logic.

- Move the code for removing outdated entries at rateAggrState into removeOldEntries() function.
  This make the code logic inside rateAggrState.flushState() more clear.

- Do not write output sample with zero value if there are no input series, which could be used
  for calculating the rate, e.g. if only a single sample is registered for every input series.

- Do not take into account input series with a single registered sample when calculating rate_avg(),
  since this leads to incorrect results.

- Move {rate,total}AggrState.flushState() function to the end of rate.go and total.go files, so they look more similar.
  This shuld simplify future mantenance.

docs/CHANGELOG.md: use new link to VictoriaMetrics cluster docs instead of old link
The old link was changed globally to the new link in the commit f4b1cbfef0 .
Unfortunately, old links are still posted in new commits :(

This is a follow-up for 680b8c25c8 .

While at it, remove duplicate 'len(*remoteWriteURLs) > 0' check in the remotewrite.Init() functions,
since this check is already made at the beginning of the function.
